In this article, an analysis is conducted on the flow over a circular cylinder enduring torsional motion immersed in viscous fluid. The thermal energy distribution examined for constant and variable surface temperatures. problem formulated axisymmetric Cattaneo–Christov double diffusion theory, wherein equation modified. Note that rotation of axially dependent, phenomenon wall jet arises due to dependent velocity component, mainly because axial pressure gradient. Using appropriate variables, dimensionless ordinary differential equations are developed by governing partial equations. To solve them, we implemented built-in function MATLAB, namely, bvp5c. It perceived peak rises enhancing values Reynolds number Re; however, azimuthal reduces. impact pertinent parameters solutal transport fluid also studied. general, it seen they reduce heat mass transfer rates according their physical influence flow. Moreover, swirl wall-shear stresses plotted as Re range 0.01 ≤ 104.
